lightsaber help

here is my problem, im using the node setup here:

but when i try to composite the lightsaber into an image, it darkens the image, and trying to combine two different lightsabers screws up the whole thing.

here is my node setup


i can post pics of the results etc. if needed…

Hmm, mix them at 50% and then use a dodge node fac 1.00. I was playing with nodes earlier and it fixed my problem.

ok, i figured it out, my color ramps for the lightsabers needed to have an extra control point at the end (so the color doesn’t bleed on the background, which was halve the problem) then the lightsabers needed to be mixed with “screen” then the lightsabers and background where also mixed with “screen” and it works!
